An absent parameter is indicated by actual->expr == NULL.

On linux and FreeBSD (4.8) clock() returns a clock_t. On 64-bit targets 
(x86_64) this is is a "long", so can return values > INT_MAX. It can also 
return negative values.

Also, clock() returns CPU time, SYSTEM_CLOCK should return real time.
